There are 52,160 students. There are three magazines that the students buy. There are 3,250 that buy all three magazines. How many students buy just two of the magazines? Here is the number of students that buy each magazine:
Magazine #1: 23420
Magazine #2: 24130
Magazine #3: 25570

My thoughts

How I figured his problem out was by adding up the students from each magazine to get 73,120. Then I subtracted the total amount of students from the total I got from all three magazines 73,120-52,160. Then I subtracted the 3250 from that answer. 73,120-52,160-3250=17,710. Is thiscorrect?
